Comment 1 for bug 1672441

Tried 3 times to replicate this with Xubuntu - other than once instance of it being a bit 'slow' to get to the remove and hit enter dialogue - all worked as expected.

Tried with Ubuntu - got a cursor in top left corner. No dialogue. Hit enter and it did reboot.

Tried with Ubuntu - got the remove and enter dialogue - however while this instance was installing apport told me that qemu had crashed. ( https://bugs.launchpad.net/ubuntu/+source/qemu/+bug/1672531 just in case that's helpful here)
